(c)Major assets. A management official of a depository organization with total assets exceeding $2.5 billion (or any affiliate of such an organization) may not serve at the same time as a management official of an unaffiliated depository organization with total assets exceeding $1.5 billion (or any affiliate of such an organization), regardless of the location of the two depository organizations. The Board will adjust these thresholds, as necessary, based on the year-to-year change in the average of the Consumer Price Index for the Urban Wage Earners and Clerical Workers, not seasonally adjusted, with rounding to the nearest $100 million. The Board will announce the revised thresholds by publishing a final rule without notice and comment in the Federal Register.
